Go into your inventory screen, click on a piece of gear, then select the "equip" button

Sorry, I couldn't resist :P

Which bosses in particular? That can make a pretty big difference in what to gear for.

I always get help from the cheap seats.     lol

I need a lot of help with Dark Fae.  Lets start with her.  

Then don't use demytha lol

More trolling help arrives!

Deacon alure & fast  blue atk based nukers

Yep. Thor is exceptionally good for Fae too

HH says Demy is great for Dark Fae.  I am beginning to wonder why I pay attention to him.  

The forum needs to become CC.  The advice is better. 

Which DT boss can Demy beat up?

I don't know if there's any that she's specifically best for. Personally I don't think I use her anywhere outside of CB.

Same for me. I use her on my demon lord team, where the only thing that matters is her speed. I've probably used her once or twice for random sin city stages, but shes not on any of my boss teams

I have a speed tuned all affinity CB team.  Sounds like Demy will go back into storage.  

To be fair that's the entire group of forum regulars

She won't really be good outside of a healer / support option for any boss but even for that there are better options for every boss. 

I don't use Demytha at all.  

Demy will turn into Alure and start a new thread.
